Lutetium-177 is used as an active pharmaceutical ingredient (API) in the manufacture of therapeutic radiopharmaceuticals. Supplied typically as lutetium-177 chloride (¹⁷⁷LuCl₃), it serves as a radioactive precursor that is chemically bound to targeting molecules including peptides or antibodies. Once administered, the beta radiation emitted by Lu-177 delivers localized cytotoxic effects to diseased cells (e.g., tumor cells), making it a key API in targeted radionuclide therapy products. It is grouped under the following drug class(es): Radiopharmaceuticals. The directory classifies it as a commercial API with a mineral/inorganic source/manufacturing origin. Other names for this substance include 177Lu radioisotope and Lu-177. Its PubChem CID is 161046.
